Electrical distribution boards contain a special circuit breaker, which is the main part of these board panels. It has the main function which includes splitting the total amount of electrical power and distributing it to a certain number of mini circuit breakers. Each of the mini breakers are connected to a specific cable that leads to an individual power outlet, machine point or light circuit. These cables are also inserted in the distribution board, but they are located on the opposite side of the main feeding cable.
Other components of the electrical distribution boards
– bus bar
– fuse links
– bypass equipment
– residual current detector.
The bypass equipment is in fact a combination of special protection components that protect the electrical connections within the distribution board from common problems such as short-circuiting, power overloading and similar.
The residual current detector (RSD) provides great protection against fire and ground fault shock.
The structural and technical characteristics of the electrical distribution boards may vary. In general, these devices are manufactured to match the requirements and specifications of specific regulations. Adding new or replacing the old components with devices that are neither tested nor approved and regulated may pose a very dangerous threat to the safety of the electrical system in general, as well as to the safety of the people inside the building.
